8% Rule Is Triggered: How I’m Adjusting 2 Positions

Many readers are aware of my 8% rule. Some newer readers have asked about panic points and that rule. Now, followers of the $10,000 Portfolio will see how I handle this specific discipline in real time.

The deal is this. It stems from a trade gone wrong way back during the days of the dot-com bubble, or rather the bursting of that bubble. The nearly 100% loss of principle on a long position in internet incubator CMGI ultimately led to my working for myself so I could set the rules. That event also led to my creating a set of disciplines that I could live with and in a perfect world, prosper by.

The bottom line is that unless the loss happens while I am sleeping, I have promised myself never to take a loss of 8% or more without taking action of some kind. Readers should be aware that I do exempt lower-priced stocks from the rule. That’s why long-term readers who focused upon the old “Stocks Under $10 Portfolio” and transitioned to the $10K Portfolio may not have ever had to deal with this rule in the past, unless they also tracked other moves of mine that impacted the broader “Sarge-folio.”

What’s Going On?

Despite the fact that the $10K Portfolio is indeed in the green since its inception in March, we have two stocks that are now in violation of my 8% rule based on when this portfolio, not the broader Sarge-folio, entered into those positions. It gets a little confusing as I often have to keep more than one average point of entry, but this is an educational portfolio. Hence, I would be remiss in fulfilling my responsibilities to you, my readers, if I did not make an earnest attempt to show newer or less comfortable investors how professional managers go about their business.

Now, panic points do not automatically cause a fire sale. They are a call to action. This portfolio is now down roughly 17% on Planet Labs (PL). I have already been adding to this long and will add again as I have a fairly high level of conviction in the name.

Meanwhile, Palantir Technologies (PLTR) is an old darling of ours as our $8 entry point made this portfolio’s predecessor the legend it became. That position, gasp, is now down 8% and I intend to create some cash without exiting the name completely.
